WINDOW.

SPECIFICATION forming part of Lettersatent No. 602,885, dated April 26, 1898. Application filed May 26, 1896. Renewed March l1, 1898. Serial No. 673,541. (No model.)

To all whom it may concern:

Beit known that I, FRANK VITTNER, a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in lVindows; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

The invention relates to windows, and has for its object to adapt them to be opened by swinging the sash laterally as well as by raising or lowering the saine, and to provide for easily removing the sash from the casing; and the invention consists in the construction hereinafter described and particularly pointed out.

In the accompanying drawings, Figure 1 is a front view of my Window, the upper and lower sashes being adapted to be moved down and up, respectively, in the usual manner, each sash being closed and in its normal situation. Fig. 2 is a section on line 2 2 of Fig. 1, but

with the movable leaves of a hinge swung into position and engaged by pins on the lowersash. Fig. Sis afront View of the hinge in the saine position as in Fig. 1, but on a larger scale. Fig. 4 shows the same hinge with both leaves in the same plane. Fig. 5 is a side View, on a larger scale than in Fig. 1, of one of the hooksv for securing a separable side sash-bar either to the sash or to the window-frame and showing ahook-case with parts broken away. Fig. 6 is a similar View showing the case in placeon the separable side sash-bar and seated in the window-frame, the pivoted hook being in a position the reverse of that illustrated in Fig. 5. Figs. 7 and 8 are side views of dierent forms of double hooks. Fig. 9 is an enlarged section on line 9 9 of Fig. l. Fig. 10 is an elevation of a window, the lower sash being partly open and the situation of the fixed leaf of the hinge modified. Fig. 11 is a section on line 11 11 of Fig. 10, both sashes being closed and arranged side by side and slightly raised, as necessary to engage the pins with the hinges, as indicated. Fig. 12 is an enlarged section of the lower part of the window, the sash being disposed as represented in Fig. 11. Fig. 13 is a section on line 13 13 of Fig. 12. Fig.

14 comprises a plan'and elevation of a pinsupporting plate. Fig. 15 is a partial horizontal section of a modification.

Numeral 1 denotes a Awindow-casing.

2 indicates the upper sash, and 3 the lower.

Li denotes detachable parts or sections of the sash sides. These are connected to the xed portions of the sash sidesby scarf-joints, (shown at 5,) and arenormally held in fixed relation thereto by the armsof double or twoarrned hooks 6, which engage pins 7, fixed in the sash side, the hooks being so formed as to engage the pins securely. The sash side being sectional, as described, its sections can be separated in horizontal lines transverse to the joint 5, and so that the separable section 4 may remain connected to the windowframe, while the sash, with its fixed side section, is swung open. The sash-weights are connected to the parts 4 ot' the sash sides by suitable cords (indicated by dotted lines at 20) and tend to hold the hooks engaged with the pins.

8 indicates cord-grooves.

The outer arm of each of the double hooks 6 may when desired be made to engage a pin 9 on the window-casing to hold the separable pieces 4f of the sash sides in the window-casing when the sash is turned on its hinges to swing it open. The form of the double hook may be varied, as indicated in Figs. 7 and 8.

10 denotes hinges, one leaf 10 of -each of which is fixed in the window-casing, while the other is normally free. The swinging leaf of each hinge has an open slot 11 in its upper end, and this leaf can be turned parallel with the front face of the sash side in position to receive a pin 7 fixed inA the sash, when the latter has been slightly raised to carry the pins above the level of the leaf and then lowered to drop the pins into said slot 11. The sash being thus hinged and raised above the sill can be opened, the button-hooks having been suitably moved to allow the sash to separate freely from the side pieces l at the scarfed joint.

Each hook 6 is preferably inclosed in a casing or box 12, suitably slotted to permit the ends ofits arms, which extend outside the case, to move freely.

The sash-hook boxes or eases 12 are let into IOO the separable piece 4 at 13, so that the outer surface of the box is in the same plane as that of the outer surface of the sashes. The pins 7 may be fixed in shallow recesses 14 in the sash, and need not extend outside its surface to interfere with moving either sash up or down to any desired extent.

The device would with care operate if the pins were without heads, as shown in Fig. 1

and elsewhere, as the weight of the sash will tend to prevent it from being pushed off from the pins; but for entire safety headed pins, such as indicated in Figs. 11 to 15, are preferred.

In Figs. 12 and 13 is shown one of two hinges for the lower sash, having its iixed leaf or partcomposed of. an angle-iron 18,-one side of which is screwed to the stile of the casing and the other to the front strip 19. The movable part or swinging leaf of the hinge is shown as engaged with a headed pin 7 fixed in a plate 21, let into and attached to the side rail of the sash. 22 denotes a parting-strip, to which and to the adjacent stile of the casing are secured similar hinges for the upper sash, the construction'being like that just above described. Each sash has two hinges, the upper andlower hinges Vbeing preferably on the same level. The lower sash can be slightly raised, as before stated, and its pins dropped into the slots of the swinging leaves of the hinges and then opened. The sash 2 can be lowered to the level of sash 3,'as indicated in Figs. 11 to 13, and opened in like manner, saidlower sash having been first opened by turning on its hinges or by entire removal.. If desired, the sash 3 can be moved entirely above sash 2 when lowered to the sill. For this purpose a slot 23 may be provided in the casing.

Various details may be varied without departing from the invention, provided the essential principles of construction and operation are preserved. It is, however, practicable and preferable to attach the hinges to the inner face of the stile without cutting entirely through it, as shown in Figs. 9, 12, and 13. These and like changes are considered to be withinthescope oftheinvention. Forfurther example, the upper sash may be hinged at or near itsnormal level, as indicated in Figs. 1

and 9, an opening through the stile into the cord-channel being provided for the movable leaf of the hinge. It is not in this form necessary, however, to cut entirely through the stile, it being only necessary to providea pocket to receive the swinging leaf of the hinge when the latter is inoperative, as indi; cated at 16 in Fig. 9.

One modication contemplated is indicated in Fig. 15, in which 25 denotes a separable part of a sash side detachably connected to the stile by a hook 25', adapted to engage a pin 26 in the stile and provided with a thumb pin or bolt 27, which serves as apivot for the hook, the stile and separable part of the sash being suitably slotted to receive the hook, operating as stated. 28 denotes a hinge of common form. The sash can be swung open about the pintle of these hinges, the opposite side sash having been freed from the retaining-strip or the strip removed.

Having described my invention, what I claim is'- l. In a window the combination of the casing, a sash having a side made of a fixed and aseparable section, said casing and fixed sash side section having each a pin, and a hook pivotally supported in the separable section and adapted to fix the separable section either to the sash side or to the casing by means of said pins, the two sash-sections being horizon tally separable,substantially as described.

2. In a window the combination of the casing, a sash having a side made of a fixed and a separable section, said casing and iixed sash side section having each a pin, a hook pivotally supported in the separable section and adapted to iix the separable section either to the sash Side or to the casing by means of said pins, the two sash-sections being horizontally separable, and a hinge on the opposite sash side, substantially as described.

3. In a window the combination of the casing, a sash having a side made of a fixed and a separable section, said casing and fixed sash side section having each a pin, a hook pivotally supported in the separable section and adapted to iix the separable section either to the sash side or to the casing by means of said pins,ithe two sash-sections being horizontally separable, and sash-weights connected to the detachable section and adapted to hold the hooks engaged with the pin either on theiixed sash-section or on the casing, substantially as described.

In testimony whereof I have signed this specificationfin the presence of two subscribing witnesses.`v`
